Well Fuzzy, you're a party pooper!
I had not thought of that...was so stoked about easier oil/primary/trans changes.
But you make a VERY GOOD point about inspecting the magnet.
My Flo-n-Go was delivered today, and is sitting in my home office...I might use it every other oil change, as you suggest, but I don't think I will on the primary/trans. I do like to see what is on the magnet.
....OR...I may still use it, and when it is "dry" pull the plug then and look at/clean the magnet. We'll see.
I've Never seen sludge in a drain for decades...not too concerned about that.
A big Thank You for the heads up!
